{"id":"CVE-2026-111755","published":"2026-10-19T18:17:00.260","lastModified":"2026-10-19T21:13:39.973","description":"follow-redirects is a Node.js HTTP and HTTPS client wrapper that automatically follows redirects. From 1.16.0 until 1.16.1, escapeRegex leaves valid header-name metacharacters unescaped in sensitiveHeaders. When an application declares a sensitive header whose name contains ^ or | and follows a cross-origin or HTTPS-to-HTTP redirect, unescaped regular-expression metacharacters prevent the generated filter from matching the declared header name, and the credential header is forwarded to an attacker-controlled redirect target. This issue is fixed in version 1.16.1.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-185","CWE-200"],"vendors":[],"products":[],"references":[{"url":"https://github.com/follow-redirects/follow-redirects/commit/080a76d0e125b37bf81717368a61d5dc37aa56c8","tags":[]},{"url":"https://github.com/follow-redirects/follow-redirects/releases/tag/v1.16.1","tags":[]},{"url":"https://github.com/follow-redirects/follow-redirects/security/advisories/GHSA-8r9p-f939-6h3c","tags":[]},{"url":"https://github.com/follow-redirects/follow-redirects/security/advisories/GHSA-8r9p-f939-6h3c","tags":[]}],"exploitRefs":[{"url":"https://github.com/follow-redirects/follow-redirects/commit/080a76d0e125b37bf81717368a61d5dc37aa56c8","tags":[]},{"url":"https://github.com/follow-redirects/follow-redirects/releases/tag/v1.16.1","tags":[]},{"url":"https://github.com/follow-redirects/follow-redirects/security/advisories/GHSA-8r9p-f939-6h3c","tags":[]},{"url":"https://github.com/follow-redirects/follow-redirects/security/advisories/GHSA-8r9p-f939-6h3c","tags":[]}],"hasPoc":true,"ai":null}
